Python is not a great language for data science

Summary

Yes, I’m ready to touch the hot stove. Let the language wars begin.Actually, the first thing I’ll say is this: Use the tool you’re familiar with. If that’s Python, great, use it. And also, use the best tool for the job. If that’s Python, great, use it. And also, it’s Ok to use a tool for one task just because you’re already using it for all sorts of other tasks and therefore you happen to have it at hand. If you’re hammering nails all day it’s Ok if you’re also using your hammer to open a bottle of beer or scratch your back. Similarly, if you’re programming in Python all day it’s Ok if you’re also using it to fit mixed linear models. If it works for you, great! Keep going. But if you’re struggling, if things seem more difficult than they ought to be, this article series may be for you.I think people way over-index Python as the language for data science. It has limitations that I think are quite noteworthy. There are many data-science tasks I’d much rather do in R than in Python. I believe the reason Python is so widely used in data science is a historical accident, plus it being sort-of Ok at most things, rather than an expression of its inherent suitability for data-science work.At the same time, I think Python is pretty good for deep learning. There’s a reason PyTorch is the industry standard. When I’m talking about data science here, I’m specifically excluding deep learning. I’m talking about all the other stuff: data wrangling, exploratory data analysis, visualization, statistical modeling, etc. And, as I said in my opening paragraphs, I understand that if you’re already working in Python all day for a good reason (e.g., training AI models) you may also want to do all the rest in Python. I’m doing this myself, in the deep-learning classes I teach. This doesn’t mean I can’t be frustrated by how cumbersome data science often is in the Python world.Thanks for reading Genes, Minds, Machines!
